objc:alloc-init-object

(objc:alloc-init-object class)

(objc:invoke (objc:invoke class "alloc") "init"): a new instance of class, a class pointer or its name. Part of the macOS-only objc package -- the interpreter (java -jar, or the rontolisp native binary), a compiled .class / .jar and a --native executable for macOS on Apple silicon, never a .wasm; on a machine without the runtime it signals an error. See the macOS GUI guide.
